Title: Improvements in or relating to rotary jars for use in well drilling operations
IPC: E21B31/107
Filed: 1947-03-12
Abstract: 622,341. Well-drilling jars. BOYD, F. C., and BUTLER, W. O. March 12, 1947, No. 6892. Convention date, March 18, 1946. [Class 85] Relates to jars for loosening stuck drills &c. in well-drilling and comprises a mandrel mounted in a housing for relative longitudinal and rotational movement, and restraining means adapted to hold said mandrel and housing against relative rotation while torsion is applied, the restraining means being then freed and the torsion causing relative rotation to cause a hammer member on one of the parts to strike a blow in a rotary direction against impact means on the other part. In Figs. 1 and 6, a housing 18 secured to drill pipe &c. contains a mandrel 20 connected to the stuck drill &c. and has a lug 21 adapted to engage a flute 45 in the mandrel to hold the parts while torsion is applied to the drill pipe as by the rotary table; the housing is then raised to free the lug 21 which, under the torsional effect, rotates to strike an impact member 22 longitudinal of the mandrel. To facilitate assembly, the upper end of the mandrel is initially provided with a flute similar to the flute 45, and the housing 18 is formed in two parts 18a, 18b; the mandrel is inserted in the part 18a, the flute in the upper end of the mandrel is filled with welding metal and said upper end is threaded to receive a guide collar 24 and wash pipe 41 with packer 39, and the parts 18a, 18b are welded at 23. Upward or downward blows may be effected through shoulders 31, 32 or 26, 28. In Figs. 8 and 9, the housing 58 has a lower end 58a with a reduced bore provided with steep internal threads 61 co-operating with threads 62 on the mandrel 74 which has a hexagonal part 75 slidable in a corresponding hexagonal bore in a sleeve 80 secured to the stuck drill etc.; the housing 58 and sleeve 80 have cam ends providing dogs 98, 99, which are engaged to hold the parts while torsion is built up in the drill pipe &c., the housing 58 then being raised to free the dogs 98, 99, when the torsion rotates the housing to cause housing end 58a to give a blow with a vertical component acting through mandrel head 66 and a horizontal component acting through threads 62. In Fig. 12, the mandrel 60 and housing 58 have a similar threaded connection 61, 62, but the mandrel is directly connected to the stuck drill &c., and carries a lock sleeve 80a slidable on splines 107 against resistance of a spring 108, the lock sleeve having an inclined dog 99a cooperating with an inclined dog 98a on the lower end of the housing 58; application of excessive torsion to the drill pipe is prevented by relative sliding movement of the dogs 98a, 99a.

Abstract: 138,747. Cozatt, W. R. March 20, 1919. Matrices for type-casting machines.-Relates to matrices for casting faces in metal strip material for printers' rules, and particularly to matrices of the kind having exchangeable parts to enable different styles of printing-face to be cast. The matrix comprises a holder 1, Figs. 1 and 2, provided with a recess having undercut ends 3 to receive face liners 8 and space liners 7, Fig. 4, adapted to form the rule face desired, the sides of the matrix being formed by packing-pieces 4. The packing-pieces are of such thickness that, when assembled with the liners, they project slightly beyond the sides of the holder and are pressed inwards by the packing-pieces of adjacent matrices so as to fit tightly against the liners. One end of the holder is provided with a recess 11 to per. mit the rule face to pass, so that a rule of any length can be formed by casting successive sections and moving them past the end of the holder. The holder is formed with a slight taper so that the rear portion of the casting is higher than the front, the high portion being pressed or smoothed down as the casting is moved forwards. The liners may be tapered instead of the holder for the same purpose. The space liners are provided with inclined casting-faces so that the rule cast has, as heretofore, a backing of greater thickness than the face. The packing-pieces extend slightly above the ends of the holder, so that a small space is left for the escape of air between the matrix and the mould.

Title: Improvements in the construction of feathering paddle wheels, in particular for aerodynamic purposes
IPC: B64C39/00
Filed: 1933-03-09
Abstract: 403,253. Wind motors. STRANDGREN, C. B., 14, Rue Gallieni, Versailles, France. March 9, 1933, Nos. 7166 and 7167. Convention dates, March 11, 1932 and Jan. 25, 1933. [Class 110 (iii).] A feathering paddle wheel or wind motor has its blades connected to the hub by flexible members such members extending in pairs in opposite directions and in substantial alignment from the same points on the hub so as to balance out the centrifugal and aerodynamic forces acting on the hub. In one form, Figs. 1 and 2, two feathering paddle wheels are carried by a transverse shaft 3 supported above the body of a flying machine by struts 2. Each wheel comprises a hub 4 built up from sheet steel plates and having secured at its periphery a number of attaching members 8, Fig. 3. To each member 8 are attached two sets of diverging flexible connecting members 9, 9a, 9b, Fig. 2, each member such as ab, Fig. 1 of one set being substantially in line with a member such as cd of the other set. These members may be cables or wires of circular, oval, or willow leaf section. At their outer ends members 9, 9a, 9b of each set are attached to forked brackets 10, 10a, 10b to which a wing 11 is pivoted on an axis 12. Brackets 10, 10b are secured to collars 13 by which they are connected to elements of a polygonal or circular belt 14 which is built of metal tubes and serves to maintain the wings in position when the wheel is idle and to prevent lateral wing movements. The wings are feathered about pivots 12 by cables 14, 15 attached to the ends of a lever 20, Fig. 3, which is oscillated during rotation of the wheel by means of a roller 24 engaged in a cam slot 23 formed in a radial arm 22 of lever 20. Roller 24 is carried by an eccentric member 25 rotating with the hub. Fig. 6 shows an arrangement in which a double hub A, B is used. A wheel having only four wings may have each wing braced to the corners of a small central rectangular frame. In the case of a five-wing wheel this frame may be pentangular or circular. In the case of wings of large span it is necessary in order to avoid using three or more hubs to provide means for bracing the wings against bending moments due to centripetal acceleration or to aerodynamic loading tension bracing only being used. Bracing members connecting each wing to its adjacent wings only may be used. A multi-hub wheel may be braced against lateral wing movement by wires connected to fittings on the propeller shaft spaced inwardly from the outermost hubs,

Inventor: LANGMEAD ROBERT
IPC: D06F31/00
Filed: 1956-03-12
Abstract: 835,250. Clothes washing machines. ARMSTRONG & CO. Ltd., J. March 8, 1957 [March 12, 1956; May 9, 1956], Nos. 7633/56 and 14387/56. Class 138 (2). Clothes are washed by continuously passing a weak, premixed detergent solution, fed to the top of the wash tub, through one or more washing machines independently, each of which machine is steam heated and has a rotary, perforated washing receptacle, a constant volume of liquid being maintained in the machine, and the supply of detergent, steam and rinsing liquid to each machine being controllable independently.

Filed: 1958-03-10
Abstract: 918,841. Boreholes. IRAQ PETROLEUM CO. Ltd. March 9, 1959 [March 10, 1958], No. 7681/58. Class 85. [Also in Group XXIX] Fluid, such as gas or oil from a well, flowing in a tube 10 passes to a valve seat 12, via the annulus between a cylindrical movable closure member 14, having two sets of guide fins 15 and the tube 10, and an orifice formed by the latter and an annular ring 18 carried by the member 14. Two bridge pieces 13 arranged transversely of the tube 10 support the member 14 when the rate of flow through the tube is below a given value, but when this flow rate is exceeded the pressure difference across the member 14 caused by pressure drop across the annulus and orifice is sufficient to overcome the weight of the member 14, and urge it on to the seat 12. By using rings 18 of different diameter any desired flow rate may be obtained. Alternatively, the member 14 may be loaded by a spring or by a fluid acting on a piston in the member, which piston is connected to the tube 10. The closing movement of the member 14 may be varied by altering the length of the latter and/or the distance of the bridge pieces 13 from the seat 12. The member 14 embodies an axial bore 20 housing a mandrel 21 which may be removed to enable instruments, e.g. pressure gauges or thermometers, to be lowered to the well bottom.

Title: Power wrench
IPC: B25B23/143
Filed: 1975-02-24
Abstract: 1472235 Power wrenches ROBERT BOSCH GmbH 24 Feb 1975 [1 March 1974] 7683/75 Heading B3N A torque-limiting power wrench comprises a motor, which may be electric, or as shown air motor 8, Fig. 2, and a transmission including a driving portion 20, 21a and a driven portion 30, Fig. 3, one of which (20, 21a) has one or more radially movable members, balls 26 biased radially of its rotational axis to bear against an internal cam surface 31 of the other portion (30), the two portions normally rotating together until excessive reaction torque causes the balls to ride up the cam surface against the action of springs 24 and the portions to move relatively to each other. This relative movement actuates means responsive thereto to cut-out the motor. In Figs. 2-4, a disc 35 integrally connected to an adjustable threaded stud 34 screwed in output tool spindle 28 has a pivoted lever 40 which covers a bore 42a in the disc when it is biased against a stop 41 on driving portion 20, 21a by spring 42 under normal conditions, thus preventing axial movement of control rod 14 which would shut-off the motor air supply. Excessive torque reaction and hence relative movement of the drive portions moves lever 40 away from the bore 42a to allow the controlrod to shut-off the motor. The particular torque at which this occurs may be set by altering the relative position of lever 40 to bore 42a by rotating stud 34 by a tool, not shown, engaging a slot 36, within limits determined by stop 37 on spindle 28 engaging a slot 38 in disc 35. The transmission assembly is slidable relative to rod 14 in its shut-off position and to the housing, but moves the rod to switch on the motor initially when the tool is brought into contact with the work. In the alternative of Figs. 5 and 6 a spring- loaded slide controls the movement of rod 114 and is operated by a "rope" 161 connected to adjustable stud 134, relative movement of driving portion 121a and driven portion 130 acting on the rope and lifting the slide. The wrench of Figs. 5 and 6 may have torque limitation in either rotational direction provided the cam surfaces 131 on portion 130 are suitably formed.

Title: Improvements in or relating to phase shifting networks
IPC: H03H11/20
Filed: 1937-03-16
Abstract: 490,553. Phase modulation. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. March 16, 1937, No. 7684. Convention date, March 16, 1936. [Class 40 (v)] Relates to networks for producing phase change substantially without producing amplitude change, and the use of such networks for phase modulation. In one embodiment, Fig. 3, comprising input terminals 1, 2 and output terminals 3, 4 two impedances Z are connected between the terminals 1, 3 and the terminals 2, 4 are connected together, the anode-cathode path of a valve 10<1> being connected between the junction of impedances Z and the junction 2, 4. The series-connected secondaries of transformers T feed the valve grid, their primaries shunting the impedances Z. In a second embodiment, Fig. 4, two valves 10<1>, 10<11> are shunted across the network, their grids being fed from the secondary of a single transformer T2 the primary of which is shunted across an impedance 2Z connected between the terminals 1, 3 and between the valve anodes. The phase shift may be varied by variation of the transconductance of the valve or valves, and several networks may be connected in cascade to increase the phase shift. The terminating admittance may comprise a valve 20, Fig. 5, identical with the valves in the phase shifting network, the control grid 22 and anode 24 being tied together and connected to the network terminal 3 and the cathode 21 to the terminal 4. In a practical embodiment, Fig. 8, used for phase modulation, a master oscillator O feeds a network comprising an impedance Z and valve 70 the grid of which is connected through a condenser to one end of impedance Z and the anode to the other. The potential of the grid of valve 70 is controlled by the modulating source C.P. and the output of the phase shifter supplied to amplifiers and/or frequency multipliers A, AFM. The valves are preferably of the screen grid type or their interelectrode capacities may be neutralized by known means.
